The Claim

Creatine supplementation, including creatine monohydrate and other forms, does not increase the frequency of reported side effects compared to placebo across diverse human populations, including children, older adults, healthy individuals, and medically managed patients, based on a pooled analysis of 685 clinical trials involving 12,839 creatine-supplemented and 13,452 placebo-treated participants, with 4.60% of creatine users and 4.21% of placebo users reporting any side effect.

In plain English

Taking creatine — whether it's the common monohydrate type or another form — doesn't seem to cause more side effects than a fake pill, even in kids, older adults, healthy people, or those with medical conditions.

What the research says

1 study
  1. Study: Safety of creatine supplementation: analysis of the frequency of reported side effects in clinical trials

    The study looked at thousands of people taking creatine or a placebo and found almost the same number of side effects in both groups, supporting the idea that creatine is safe.
